A little bit of backstory, just in case you want some context. In the last couple of weeks the network at least internally has slowed down. As far as I can tell the only things that have changed has been new emergency lighting has been installed and some servers have been moved from a different subnet.
Anyway onto the problem / question.
We have a NaviTEK-NT tester and below is an image of one of the network ports results. I have been told the ports should be Cat5e as that is what was requested when the points got installed.What exactly is happening in the image below? As Far as I can tell it's got 2 pairs going 20M, which is about the length of the cable between the network point I use and the patch cabinet. I then have 2 pairs going around 1M, which is maybe the rough length of the Ethernet cables combined (about 0.3/0.4m * 2).
In my head this indicates that maybe their is a break or something as I'd expect 4 pairs of 20M ~ cable length. However as far as the manual is concerned I would see a red line cutting the cable if there was a break.
TLDR: In the image below why are 2 pairs 20m and the other 2 are 1m in length. What does this indicate? It should be patched up as Cat5e though I wouldn't rule out it being just a cat5.
If I have missed anything let me know and I will try and find out anything else that could help. Thank you very much.
